What sz tires for xdrive?

kzflags · 05-22-2015, 02:25 PM

Just bought new wheels with the following specs for my f30:

19x9.0" ET 35
19x10" ET 40

what sz tires do i need to wrap them with to prevent xdrive from malfunctioning. BMW recommends ~1% difference in diameter i read, so does the following work?

235/35/19
275/30/19

275 might be way too big for the rear no? pulled those tire specs from another thread so im just shooting in the dark.

I was recommended:
245/35/19 and 265/30/19

but that makes it almost 6mm difference in diameter. No go correct?

245 - 275 will keep you within BMW's marginal spec.
